Learning and Teaching Methods
The module consists of a lecture and exercise classes.
In the thematically structured lecture the learning topics is presented. With cross references between different topics the universal concepts in physics are shown. In scientific discussions the students are involved to stimulate their analyticphysics intellectual power.
In the exercise (ca. 68 students) the learning content is deepened and exercised using problem examples and calculations. Thus the students are able to explain and apply the learned physics knowledge independently.

Module Exam
Description of exams and course work
There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
 Calculate the spectrum of eigenfrequencies for the longitudinal vibrations of the twoatomic chain harmonic chain, assuming periodic boundary conditions.
 Determine the wavefunction from the Blochcondition for the KronigPenney model.
 Calculate the density correlation function of the noninteracting Fermi gas.
 Determine the relationship between fluctuations and dissipation.
Exam Repetition
The exam may be repeated at the end of the semester.
